I have to give ~MrWizard44
credit for the inspiration. His version of the Cap is here: [link]

*Edit* I had to revisit this piece for portfolio purposes. The perspective on the beach was wrong on the previous version, and the water wasn't too believable. Fixing those main points helped the image as a whole, I think.
